APPARATUS FOR LUBRICATING THE CYLINDERS 0F STEAM-ENGINES.

SPECIFICATION forming part of Letters Patent No. 237,957, dated February 22, 1881. Application filed January 4, 1881. (No model.)

To all whom it may concern:

Be it known that I, MILTON S. GABBELL, of Quincy, in the county of Adams and State of Illinois, have invented a certain new and Improved Apparatus for Lubricating the Cylinders, &o., of Steam-Engines; andI do hereby declare the following to bea full, clear, and exact description of the same, reference being forming part of this specification, in which the figure is a view of the apparatus, partly in section and partly in elevation.

This invention relates to devices for uniformly feeding oil to the steam-chests, cylinders, &c., of steam-engines, so as to lubricate such parts properly; and it consists in certain improvements which I will now proceed to describe.

Referring to the drawing, A represents the steam-pipe of the engine, through which the oil is to be carried to the cylinder or other part to be lubricated.

B is a smaller steam-pipe, connected to pipe A and provided with a valve, (J.

D is an oil cup or chamber, from which the supply of oil is taken; E, a reservoir, from which the chamber 1) is filled. The steampipeA passes through this reservoir and keeps the oil therein at all times warm,so that it will flow readily.

F is a valve which controls the flow of oil from the reservoir through a feed-pipe, F.

G is a pipe connecting with the upper port of both the oil-chamber D and reservoir E,

and affording a vent when chamber D is being filled. Said pipe G is provided with a valve, G.

H isapipe, also connected to the larg st ampipe A, and extending down through the top of chamber D nearly to the bottom thereof, as shown.

H isa condensing-chamber, located in pipe H above chamber D; O, a valve in said pipe H 5 1, another pipe, extending up through the bottom of chamber D nearly to the top thereof, and connected, by means of a valve, K, pipe K, and glass gage L, to the steam-pipe B.

M is a glass gage attached to the oil-chamber D, for indicating the quantity of oil contained in the latter; N, a drain-cock for draining off the contents of the oil-chamber whenv desired; and J a petcock for blowing oft or emptying the pipe I.

The operation of this apparatus is as follows:

in order. drawn ott' from chamber D through the drain- K is then opened slightly, and the oil in pipe I is forced by hydrostatic pressure through valve K, and rises in the form of drops through the water of condensation in pipe K and gage L, and passes out through steam-pipe B into the main steam-pipe A, and thence to the cylinders or other parts to be lubricated.

The ejecting-pipe I is kept at all times full of oil from the i-hamberD, the oil in the latter being gradually displaced by the water of condensation from pipe H, as will be readily understood.

The amount ot'oil in oil-chamber D is at all times indicated by the gage M, and whenthe oil becomes exhausted the chamber can be refilled, as before, from the reservoir E.

By opening the valve K more or less the quantity of oil fed to the part to be lubricated can be regulated at pleasure, the gage L affording means for observing the feed.

This apparatus secures a constant and uniform supply of oil to the part to be lubricated, and, further than to observe that a proper quantity of oil is maintained in chamber D, no special care or attention is required to keep it The water of condensation can be dock N when it is required to refill the chamber with oil, and when it becomes necessary to blow oft the pipe I the petcock J, at its lower bend, can be opened.

I claim as my invention 1. In an oil -feeding apparatus, the combination of the oil-reservoir, having the valved supply-pipe and the valved vent-pipe, with the oil cup or chamber, into which both said pipes lead, substantially as described.

2. In an oil -feeding apparatus, the combination, with the oil cup or chamber, of the pipes H and I, connected with the steam-pipe A, as described, the oil-reservoir, and its supply and vent pipes, substantially as described.
